Title: Schmitt trigger circuit
Inventor: YASUDA YASUSHI
IPC: H03K3/037
Filed: 1982-03-31
Abstract: PURPOSE:To constitute a Schmitt trigger circuit at an arbitrary part, at a gate array mounted with diodes in advance, by forming the Schmitt trigger circuit for use with two inverters. CONSTITUTION:A voltage Vc at a point C is risen when a voltae at an input terminl IN is increased. When the inverter 5 is inverted, an output of an inverter 6 goes to an H level, a current through a resistor 8 flows to the point C via a diode 3 and the inverting operation is performed rapidly. When the voltage at the input terminal IN is lowered, the voltage Vc is also lowered, the output of the inverter 5 goes to the H level, then the output of the inverter 6 goes to an L level, a current flowing to the resistor 8 is given to the inverter 6 via a diode 4, allowing to assist the output of the inverter 5 transited to the H level.

Title: Method for modeling smoke density distribution in tunnel
Inventor: GOKO YOSHINORI
IPC: F24F7/007
Filed: 1994-02-26
Abstract: PURPOSE:To make the distribution of smoke visually and easily understandable and to precisely grasp the amount of smoke generation by vertically stacking a plurality of horizontal belts each having a width in proportion to smoke density thereby to model the smoke density distribution in a tunnel. CONSTITUTION:By repeating parallel movement of velocity in proportion to wind velocity in a tunnel at certain time intervals and by repeatedly stacking new smoke belts B, B' generated in the certain time interval, a smoke density distribution in the tunnel can be obtained. Next, since wind velocity in the tunnel can be obtained by an anemometer, amount of air movement (m) after a certain period of time can be obtained, so that the smoke in the tunnel parallelly moves toward the exit by the amount of air movement (m). Since the density of smoke near the exit can be measured by a densitometer, the difference AC between the measured density C1 and smoke density C2 after the movement of air can be obtained so that the amount of discharged smoke can be obtained. New smoke can be represented by a horizontal belt having a width in proportion to the difference AC, and by repeatedly forming the belt, distribution of smoke density can be formed into a model.

Filed: 1993-02-20
Abstract: PURPOSE:To prevent the occurrence of howling in an excellent way while preventing deterioration in sound quality and decrease in a loudspeaking level. CONSTITUTION:Stored data in a data storage section 22 are read by an instruction of a characteristic setting section 24 and the characteristic of equalizers 12, 14 is set by a sweep control section 18 based thereon. The center frequency in the attenuation characteristic of the equalizers 12, 14 at Q=12 is swept as 1000Hz, 500   1100Hz, 560   1000Hz, 500   900Hz, 450Hz  ... at every 10msec. The attenuation characteristic at Q=3 is equivalently obtained by the sweeping as above mentioned. When the distance between the speaker and the microphone is 10m, since it is sufficient that the signal more than 34msec does not exceed a howling level, the production of howling is prevented in an excellent way. Moreover, since the Q in the attenuation characteristic of the equalizers 12, 14 is high, the deterioration in the sound quality and the reduction in the sound volume are prevented.
